Anti-swirling composite nozzle with Al2O3-C body and Zirconia Insert-working for 6-8 hours.
Products Features:
High Quality of anti-swirling of composite nozzle with alumina body and zirconia insert we are supplying, the zirconia insert has the high purity and high density, the excellent chemical stability at high temp. state, high strength, excellent crushing resistance, erosion of the steel liquid and slag resistance, strong thermal shock stabilities, super low speed of the diameter enlargement of the nozzle, the alumina body, we take the high quality of the alumina powder and grain, with the special high quality of the production technology, produced the 2.5-2.6g/cm3 density of the composite nozzle, and increase the whole working life of the complete nozzle.
Working life of the composite nozzle
For the working life of compiste nozzle embedded Zirconia Metering Nozzle into it, used in the tundish, based on the different smelting steel types in tundish, different casting times of the furnace, the working lifes are different. Fangming NewM can produce the requested the zirconia metering nozzles according to the clients' demand for the shape and sized, the normal working life can reached 6-8continuously, even higher.
Production Process
Our supplied the compisite nozzle with 5.4g/cm3 Metering Nozzle Insert and Al2O3 Body used in tundish is taking the world's advance automatic production equipment and technology, and taking the high quality of the zirconia grain and powder, adding other additives, through the mixing, drying, inspecting, pressing, inspecting,drying, sintering,inspecting, etc. standard andsystem process, then produce the exact size, high quality,longer-working life of the zirconia lower nozzle in tundish.
